      <title>CVE-2026-40963 — Apache Airflow: DAG authorization bypass on /ui/structure/structure_data</title>
      <link>https://db.gcve.eu/vuln/cve-2026-40963</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Apache Software Foundation Apache Airflow&lt;/p&gt;
&lt;p&gt;The structure_data endpoint in the Airflow UI returned external dependency graph nodes for linked Dags without checking whether the caller had read permission on those linked Dags. An authenticated UI/API user authorized for one Dag could enumerate linked Dag IDs and dependency metadata for other Dags they were not authorized to read. Affects deployments that rely on per-Dag read scoping to keep Dag dependency topology private across teams. Users are advised to upgrade to `apache-airflow` 3.2.2 or later.&lt;/p&gt;</description>
